The transportation screw is rotatably positioned in the toner transportation pipe. A support member is attached to the rotational shaft that has a bearing portion having an annular shape and rotatably fitted onto the rotational shaft and that has a plurality of leg portions radially protruding outward from an outer circumferential surface of the bearing portion. A distance between an axis of the rotational shaft and a tip of each leg portion is greater than a radius of the transportation fin and equal to or less than a radius of an inner circumferential surface of the toner transportation pipe.
